IMPROVEMENT IN LAMP-BURNERS.

Specification forming part of Letters Patent No. 136,586, dated March 11, 1873.

To all whom it may concern:

Be it known that I, BENJAMIN F. CHAP- PELL, of Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Lamp- Burners; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, whereby a person skilled in the art can make and use the same, reference being had to the accompanying drawing and to the letters of reference marked thereon.

Like letters in the figures indicate the same parts.

My invention consists in certain devices, attached to a burner as ordinarily constructed to burn coal or other oils, by means of which the distance the wick is raised or lowered can be limited, so as to prevent its being turned too high when lighted, or too low when the lamp is extinguished.

The object of myinvention is to preveutthe wick being turned so high as to smoke when raised for lighting, or so low as to be disengaged from the spur-wheels by which it is operated, and thereby dropped into the lamp and lost, as is frequently the case.

In the accompanying drawing, Figure 1 is a side view, and Fig. 2 is a cross-section, of a burner furnished with my improvements. Figs. 3 and 4 show a longitudinal and cross section of my improved device upon a larger scale. Figs. 5 and 6 show the interior spindle and head, with the clutch for connecting with the end of the spindle which carries the spurwheels for moving the wick.

a is the wick-tube of an ordinary burner. b is the spindle that moves the spur-wheels c c for raising and lowering the wick. It is operated by means of a milled head on the end, in the usual manner. (I is a hollow sleeve, with an enlarged head, c. It is firmly attached to the body of the burner and forms part of it. f is a spindle passing through and turning in the sleeve cl. It is provided with a head, g, which has a projection or stud, h, on the inside next to c. This stud Works in a slot, t, in e, and can be moved to one end or the other, as desired, but its motion is stopped by the end of the slot. j is a spiral spring, acting upon the parts f and d so as to keep the disks 0 and g pressed together, but will yield to allow the head 9 to be drawn out from 6. k and Z are clutches upon the ends of the spindles f and b. They are connected so that the two spindles move together when the heads 6 and g are together, and the stud h is in the slot i, but are disconnected when the head 9 is drawn part way out, as shown in Fig. 3.

The operation of my invention is as follows:

When the lamp is in use the head 9 lies against e, and the stud h is in the slot t. It is turned to one side so as to lower the wick as far as possible, which is then cut off to the level of the top of the wick-tube a. When the stud h is turned to the other end of the slot 1; the wick will be raised to the proper height to give the greatest clear flame of which it is capable. If lighted in this position it will burn without smoking, and on turning it back the flame will be extinguished. When it is desired to put in a new wick, or move the wick up or down more than is permitted by the length of the slot t', the head 9 is drawn out and turned part way round; this draws the stud h out of the slot '5, and rests it upon the higher part of 0, so as to keep the clutch is l disengaged. The spindle Z) can then be turned, and the wick moved up and down in the usual manner.
